Vascular Damage Control Approach Using Direct Deployment of Self-Expandable PTFE Covered Stent as an Alternative to Intra-Arterial Shunt


Introduction: The use of intravascular shunts for damage control purposes have been well described both in the battlefield and in the civilian environment. In this report we present a case in which a self-expandable polytetrafluoroethylene (PTFE) covered stent was used as an alternative to traditional damage control intra-arterial shunt to successfully control bleeding and reestablish arterial flow in the aortoiliac segment.

Case Description: 50 year-old male presented in extremis after sustaining multiple abdominal gunshot wounds. After resuscitative thoracotomy, laparotomy demonstrated transection of the right common iliac artery at its origin, destructive pancreatic head injury with associated superior mesenteric vein (SMV) injury and duodenal devascularization, and multiple small bowel and colonic injuries. Because of the location of the injury at the aortoiliac junction, temporary intra-arterial shunt placement would not be possible as no residual iliac cuff was available to secure a tie around the shunt proximally. A self-expandable PTFE covered stent was then introduced and directed across the injury under direct visualization and deployed to bridge the defect from the aortic bifurcation to the right common iliac artery. After deployment, the stent was hemostatic and pulses were palpable in bilateral iliac and common femoral arteries. The SMV was then primarily repaired, a duodenopancreatectomy was performed and left in discontinuity, and multiple small bowel resections and a sigmoidectomy were performed using GIA staplers and left in discontinuity. The retroperitoneum was packed and temporary closure of the abdomen and left chest achieved with negative pressure dressing. Total operative time was 65 minutes. After a 4-hour period of resuscitation in the ICU, the patient became hemodynamically unstable and was re-explored. Diffuse bleeding was identified in all raw surfaces of the retroperitoneum, abdominal wall and chest wall. The area of the stent was hemostatic. The right colon was massively dilated from intraluminal bleeding, so a right hemicolectomy was performed. Despite resuscitative efforts and more than 100 units of blood products the patient expired.

Conclusion: In this report we described the use of direct endovascular repair using a self-expandable PTFE covered stent in the aortoiliac location as an alternative to temporary intra-arterial shunt placement. This technique allowed quick hemostasis and reestablishment of arterial flow in an area in which traditional intra-arterial shunts would not be feasible.
